The unit indicates the tightening torque with the
numbers “1, 3, 5 ... 22” on the clutch dial , and the
dots. The tightening toque at position “1” is the
weakest and the torque is strongest at the highest
number. (See
Figs. 5
)
(3) Adjusting the tightening torque
Rotate the clutch dial and line up the numbers “1, 3,
5, ... 22” on the clutch dial, or the dots, with the
triangle mark on the outer body. Adjust the clutch
dial in the weak or the strong torque direction
according to the torque you need.
CAUTION
The motor rotation may be locked to cease while the
unit is used as drill. While operating the driver drill,
take care not to lock the motor.
Too long hammering may cause the screw broken
due to excessive tightening.
3. Change rotation speed
Operate the shift knob to change the rotational speed.
Move the shift knob in the direction of the arrow (see
Figs. 7
and
8
).
When the shift knob is set to “LOW”, the drill
rotates at a low speed. When set to “HIGH”, the
drill rotates at a high speed.
CAUTION
When changing the rotational speed with the shift
knob, confirm that the switch is off.
Changing the speed while the motor is rotating will
damage the gears.
When setting the shift knob to “HIGH” (high speed)
and the position of the clutch dial is “17” or “22”, it
may happen that the clutch is not engaged and that
the motor is locked. In such a case, please set the
shift knob to “LOW” (low speed).
If the motor is locked, immediately turn the power
off. If the motor is locked for a while, the motor or
battery may be burnt.
Be sure to turn the shift knob.
